Title: Digital high definition video recorder having high definition display in trick-play modes
Inventor: NAIMPALLY SAIPRASAD V
IPC: H04N5/926
Filed: 1994-05-26
Abstract: ABSTRACT OF THE DISCLOSURE           A digital video tape recorder records compressed image signals which include both intra-frame encoded image slices and motion compensated encoded image slices.  The recorder receives the encoded data either in a format in which a portion of each frame is encoded using intra-frame techniques or in a format in which an entire frame of a group of frames is encoded using intra-frame techniques.  Shuffling circuitry in the recorder recognizes the intra-frame encoded slices and reorders the slices as they are recorded such that a substantial portion of the intra-coded image slices will be recovered both in normal play mode and in trick play mode.  For the one signal, these slices represent the intra-coded portion of each frame; for the other signal they represent the one intra-coded frame in the group of frames.  In one embodiment of the invention, the trick-play mode is a three-times forward speed mode and the intra-coded slices are arranged such that substantially all of the intra-coded slices are recovered in trick-play mode.

Abstract: A three-dimensional imaging system comprises two image screens, for example, television monitor screens (40, 42), ar-ranged perpendicular to one another. A beamsplitter (46), in this case a half-silvered mirror, is positioned between the two image screens (40 and 42) so as to direct both images to the same viewing location. A decoder screen (40a, 42a) is positioned between each decoder screen (40, 42) and the beamsplitter (46). Each decoder screen (40a, 42a) comprises a substrate onto which are se-cured, edge-to-edge, a plurality of elongate, parallel lenticular elements. The substrate is provided with a plurality of clean and opaque areas such that the decoder screen defines a plurality of alternating viewing positions at which the screen appears either wholly opaque or wholly clear. The two decoder screens (40a, 42a) are so arranged that the viewing positions at which one screen appears wholly opaque coincide with the positions at which the other decoder screen appears wholly clear. Then, when two im-ages forming a stereoscopic pair are displayed on the two image screens (40, 42), a viewer positioned with one eye at each of two adjacent viewing positions defined by the decoder screens (40a, 42a) will see a three-dimensional image without the need for spe-cial glasses.

Inventor: BROWN MARY E
IPC: C12Q1/34
Filed: 1995-04-03
Abstract: An immunoassay diagnostic kit,  method,  and apparatus   for  electrochemically   determining   the concentration of an analyte in a sample.  A mixture is formed which includes the sample,  an enzyme-acceptor polypeptide, an enzyme-donor polypeptide linked to an analyte analog (enzyme-donor polypeptide conjugate), a labeled substrate,  and an antibody specific for the analyte to be measured.   The analyte and the enzyme-donor polypeptide conjugate competitively bind to the antibody.        When  the  enzyme-donor  polypeptide conjugate   is  not  bound  to  antibody,   it  will spontaneously  combine  with   the   enzyme   acceptor polypeptide to form an active enzyme complex.   The active enzyme  hydrolyzes  the  labeled  substrate, resulting in the generation of an electroactive label, which  can  then  be  oxidized  at  the  surface  of  an electrode.  A current resulting from the oxidation of the  electroactive  compound  can  be  measured  and correlated to the concentration of the analyte in the sample.

Abstract: A shared buffer memory switch for an ATM switching system and its broadcasting control method are provided which can guarantee the cell transfer quality defined for each connection by maintaining the sequence order of arrival for each cell even if ordinary and broadcasting cells are mixed.      When an input cell is a broadcasting cell, bit map data showing a broadcasting destination information is read from a broadcast registration table 6 based on the routing information derived from a header information of the cell, and an address for storing the cell in the shared buffer memory is written in all the address pointer queues corresponding to all output ports shown in the broadcasting destination information, and the cell is stored in the shared buffer memory with the broadcasting destination information. In reading a cell, an address of the shared buffer memory from which the cell is to be read out is read from the address pointer queue of the address pointer queues, and the cell is output to the corresponding output port. In the case where the cell is a broadcasting cell, the broadcasting destination information attached to the cell is reset for the corresponding output port and the revised broadcasting destination information and the cell is stored in the same address of the shared buffer memory until all broadcasting destination information are reset.
